Definitions

  • the present invention relates to a vehicle and, more particularly, to an automotive vehicle which is adapted to be selectively operated with or without rails or tracks especially for public short distance passenger service.
  • German Laid-Open patent application P No. 27 19 705.3 a public passenger automotive vehicle is proposed which may be selectively utilized with or without rails or tracks with the vehicle being provided with an inherently steerable vehicle axle with steerable or turnable wheels mounted thereat and at least one inherently non-steerable vehicle axle having wheels thereon which are non-steerable relative thereto and with track-determining transverse guide rollers arranged in a zone of the vehicle axles on both sides of the vehicle wherein the inherently non-steerable vehicle axle is, in its entirety, mounted to the vehicle so that it is pivotable about a vertical pivot axis which is centrally positioned in the manner of a pivot mounting, and with spring brackets fixedly mounted to the body of the axle of the non-steerable axle which vehicle springs may be constructed as, air-cushion bellows, are horizontally movably attached to outer ends of the spring brackets.
  • German Laid-Open patent application P No. 26 28 218.8 a short distance public passenger automotive vehicle is proposed which also may be selectively operated with or without rails or tracks with the vehicle being provided with an inherently steerable vehicle axle with steerable or turnable wheels and at least one inherently non-steerable vehicle axle having wheels thereon which are non-steerable relative thereto, and with track-determining transverse guide rollers arranged in a zone of the vehicle axles on both sides of the vehicle, wherein the inherently non-steerable vehicle axle in its entirety is also mounted to the vehicle so that it is pivotal within limits about a vertical pivot axis which is centrally positioned in the manner of a pivot mounting, and wherein two longitudinal control arms, determining the transverse position of the inherently non-steerable vehicle axle, are constructed so that they are variable in length in a manner of a telescopic system and are lockable in and/or releasable from a length required for an exact transverse positioning of the vehicle axle when the vehicle travels without being bound to
  • the aim underlying the present invention essentially resides in providing a vehicle construction of the aforementioned type which provides for an improved supporting and guidance of the control elements of the vehicle.
  • ring mount segments extending concentrically to a pivot center of the non-steerable axle, are attached to outer ends of spring brackets with at least two supporting rollers being attached to an underside of the vehicle springs which rollers are oriented with their axis of rotation approximately toward the pivot center and travelling on a flat topside of the ring mount segments.
  • a shape-mating lateral guide means or lift-off safety means is arranged on both sides beside the supporting roller mounting with the guide means engaging the lateral edges of the ring mount elements and being inserted, on the freely projecting underside of the ring mount segments, in a lateral groove in a shoulder or the like.
  • roller support mounting of the springs to ring mount segments in accordance with the present invention, a ready transverse displaceability between the spring bracket and the underside of the spring is attained during a pivoting of the non-steerable rear axle of the vehicle.
  • such spring should have a certain lateral stability, that is, a spring which produces on its own, upon a transverse stress of the lower bearing with respect to the upper bearing, a counter moment or counter force which counteracts such stress.
  • the lateral guide means may be fashioned as a roller guide means with two lateral guide rollers having a vertical axis of rotation being held on each side of the supporting roller mounting.
  • the lateral guide rollers may be elastically resiliently held on one side of the supporting roller mounting in parallel to an extension of the supporting roller axis and be pressed against the lateral edge of the ring mount segments.
  • one hook shaped holding finger is arranged as a lift-off safety means with abutments being arranged at the ends of the ring mount segments at an end face side which abutments serve, in cooperation with the holding fingers, to limit the relative path of the supporting rollers toward the ring mount segments.
  • the supporting arms for the track-determining transverse guide rollers are, in accordance with the present invention, attached directly to spring brackets on the externally located sides thereof.
  • Another object of the present invention resides in providing a vehicle construction, especially for public short distance passenger service, which enables a ready transverse displaceability between a spring element support bracket of the vehicle and an underside of the spring during a pivoting of a non-steerable axle of the vehicle.
  • a still further object of the present invention resides in providing a vehicle construction which permits the utilization of vehicle springs capable of exhibiting a counter moment or counter force.
  • a still further object of the present invention resides in providing a vehicle construction, especially for public passenger service, which ensures an accurate guidance and support during operation with or without rails or guide tracks.
  • FIG. 1 is a partially schematic top view of a rail or track bound vehicle in a curved area of the track or rail with the vehicle having a pivotable non-steerable rear axle in accordance with the present invention
  • FIG. 2 is a top view of a portion of one side of the rear axle of the vehicle of FIG. 1;
  • FIG. 3 is a partial side view of a portion of the rear axle of FIG. 1;
  • FIG. 4 is a plan view of a spring bearing in accordance with the present invention in a peripheral direction of the pivotal movement
  • FIG. 5 is a cross-sectional view of the spring bearing of FIG. 4 taken along the line V--V;
  • FIG. 6 is a lateral view of the spring bearing of FIG. 4.
  • a transversely movable vehicle generally designated by the reference numeral 1, adapted to be selectively used with or without tracks or rails, is guided through a curve which includes a track or rail 16 and a vertical transverse guide bar 17 arranged on both sides of the track or rail 16.
  • the vehicle 1 includes a steerable forward vehicle axle generally designated by the reference numeral 2 at which turnable or steerable wheels 3 are mounted as well as an inherently non-steerable rear vehicle axle generally designated by the reference numeral 4 at which vehicle wheels 5 are mounted.
  • the vehicle wheels 5 are immovable or non-steerable relative to the rear axle 4; however, the rear axle 4 may be pivoted in its entirety about a centrally arranged high level axis 12.
  • Transverse guide rollers 6 are arranged forwardly and rearwardly of each of the wheels 3 in a zone of the front axle 2.
  • the guide rollers are held by way of supporting arms 7 in fixed association with a plane of the wheels.
  • a steering moment is exerted on the front wheels 3 so that the wheels 3 are always aligned in parallel to the transverse guide bars 17.
  • the wheels 3 here merely absorb standup forces and braking moments with the lateral forces being absorbed fully by the transverse guide rollers 6 and the supporting arms 7.
  • the rear axle 4 includes an axle body 9 which carries spring brackets 10 which brackets are constructed so as to be bending-resistant and extend in a longitudinal direction of the vehicle 1. Air-cushion bellows 13 are supported at end points of the spring brackets 10 on which a vehicle superstructure is in turn supported in the vertical direction.
  • the axle body 9 of the rear axle 4 is supported on the vehicle superstructure by, inter alia, triangularly disposed control arms 11 which determine the pivot center 12.
  • Supporting arms 14 are attached to externally located sides of the respective spring brackets 10 with the supporting arms in turn carrying, at external points, transverse guide rollers 15 for the rear axle 4.
  • the guide rollers 15 are arranged forwardly and rearwardly of each of the wheels 5 on each side of the vehicle 1.
  • short ring mount segments 18 are attached at the end points of the spring brackets 10 which are aligned to the pivot center 12 for the horizontal movable supporting of the air-cushion bellows 13 at the end points of the spring brackets 10. Since the rear axle needs to execute, for a normally occurring curve-traversing pivoting movement without lateral displacement on the inside of the curve, only pivotal motions within an angular range of ⁇ 2.5° about the exact transverse position of the rear axle 4, the ring mount segments 18 can be relatively short.
  • two supporting rollers 19 are rotationally movably mounted in supporting walls 21 on an underside of the respective air-cushion bellows 13 with an axis of rotation 20 of the supporting rollers 19 being aligned at least approximately toward the pivot center 12 of the rear axle 4.
  • this bearing or support arrangement it is possible to provide for a ready relative displacement between the end of the spring brackets 10 and/or of the ring mount segments 18, on the one hand, and an underside of the air-cushion bellows 13, on the other hand, during a pivoting of the rear axle 4.
  • the bearing or support arrangement is low in noise, resistant to wear and tear, and insensitive to contamination by dirt or the like.
  • ring mount segments 18 are, for the sake of clarity, illustrated as rectangles in the drawings, in reality the ring mount segments 18 are constructed so as to be arcuate in correspondence with a distance from the pivot center 12.
  • guide rollers 22 mounted with a vertical axle 23 are inserted in cylindrical or knish-like recesses on an underside of the supporting walls 21.
  • the guide rollers 22 cooperate with lateral edges of the ring mount segments 18 lying in parallel to a direction of rotation of the guide rollers 22 and ensure an exact peripheral travel of the supporting rollers 19 on the ring mount segments 18.
  • the guide rollers 22 lying on one side of the ring mount segments 18 are fixedly arranged in the supporting walls 21.
  • the corresponding guide rollers 22 are supported in a rocker 27 which, in turn, is mounted with lateral deflection ability about a pivot bearing 29 and is pressed into place by cup springs 28 in a direction toward the lateral flanks of the ring mount segments 18.
  • a downwardly oriented shoulder 24 is arranged at the lateral flanks of the ring mount segments 18 with a lift-off safety means 25 engaging beneath the shoulder 24 in a manner of a curved holding finger.
  • the lift-off safety means is also attached to an underside of the supporting walls 21.
  • the shoulders and/or the free space formed thereby are limited in a peripheral direction by abutments 26 toward both directions and on both sides of the ring mount segments 18.
  • the abutments 26 cooperate with the lift-off safety means 25 and serve for limiting the peripherally oriented displacement path of the supporting roller bearing relative to the ring mount segments 18.
